Abstract

A radially firing munition defining a longitudinal axis and comprising a nonfragmenatary hollow collar having an inner surface and an outer surface opposed thereto with a first plurality of ports extending therebetween in a substantially radial direction. An ammunition is disposed in each port of the first plurality of ports and oriented outwardly from the longitudinal axis. An ignition source is provided for expelling each ammunition from the collar in response to an ignition signal.

Claims (18)

1. A multi-directional munition defining a longitudinal axis and comprising:

a nonfragmenation hollow collar, the hollow collar having an inner surface and an outer surface opposed thereto and a first plurality of ports extending therebetween wherein the ports are azimuthally skewed relative to a radial direction;

a first plurality of ammunitions, wherein an ammunition is disposed in each port of the first plurality of ports and oriented outwardly from the longitudinal axis; and

an ignition source for expelling each ammunition of the first plurality of ammunitions outwardly from the collar.

2. A munition according to claim 1 wherein the hollow collar is generally cylindrical and has a core with a core radius, and the collar has a radial thickness less than the core radius.

3. A munition according to claim 1 wherein the hollow collar has a slanted annulus circumscribing the longitudinal axis and oriented at an angle thereto, the ports having an inlet disposed on the slanted annulus and an outlet disposed on the outer surface of the collar.

4. A munition according to claim 3 having from 16 to 24 circumferentially spaced ports.

5. A munition according to claim 4 wherein at least two of the circumferentially spaced ports are unequally spaced from adjacent ports.

6. A munition according to claim 5 wherein the circumferentially spaced ports have different sizes such that ports having larger sizes are spaced relatively further from adjacent ports than ports having smaller sizes.

7. A munition according to claim 4 wherein the ports are disposed at an angle of 35-60 degrees relative to the longitudinal axis.

8. A multi-directional munition defining a longitudinal axis and comprising:

a nonfragmenation hollow collar, the hollow collar having an inner surface and an outer surface opposed thereto and a first plurality of ports extending therebetween from an inlet to a corresponding outlet in a substantially radial direction;

a first plurality of bullets, wherein a bullet is disposed in each port of the first plurality of ports and oriented away from the longitudinal axis;

an ignition source for expelling each bullet of the first plurality of bullets outwardly from the collar; a barrel juxtaposed with a respective inlet of the collar and extending radially inward towards the longitudinal axis and a bullet inserted into the barrel to be expelled away from the collar in response to an ignition command activating the ignition source; and

a cap interposed between a respective barrel and joined to the collar at a respective inlet, the cap and respective barrel being removably joined together.

9. A munition according to claim 8 wherein each cap is removably attachable to an inlet of a collar with a bayonet fitting.

10. A munition according to claim 9 wherein at least two bullets of the first plurality of bullets have mutually different calibers.

11. A munition according to claim 10 having an even number of ports and relatively smaller caliber and relatively larger caliber bullets alternatingly disposed therein.
